Appleinsider claims that Apple will be building in Virtual Desktop support into Mac OS X by 2004.

Appleinsider points to an Exposé hack that shrinks all windows into a small window as evidence of ongoing work on this feature.

"Virtual Desktops" is a feature that was popularized in Unix windows managers, allowing users to invoke any number of virtual screens for improved window management. CodeTek currently offers a trialware application called VirtualDesktop which implements this functionality on Mac OS X.
